.The invention isillustrat'ed as embodied in connection with a metallic'double hung window construction which includes a frame having a header ID, a sill I2 andtjambs I4 and double, hung sashes Hi and lB,-which may be of anydesired constructionas, for instance, such as shown in the drawings,*by way ofrexamplemteatures or such construction being substantially shown and i described in United States Letters Patent No. 2,257,123, dated September 30, 1941 and N0. 2304;063, datedDecemberiS; l-942, and including weather strip sealing means 211 between the header and the upper rail of the upper sash, weather sealing means 22 between the sill-and lower rail of the lowersash l8, and weather sealing means between the jambs and side sash rails which may be such as shown and described 'inUnited States Letters Patent 2,250,723, dated July 29 1941. The meeting rail 24 of the upper sash is provided with an inwardly and upwardly extending flange 26havingan inclined face 28 that extends substan ti-ally the width of the sash. The upper or meeting rail of the lower sash is provided with a complement'al flange 1 30 i that extends outwardly anddownwardly substantially the width of the sash and is provided-*witnan inclined f acec32 that is complemental to the race 28 and is adapted to have pressure surface contact therewith when the sashes-are closed, thus providing one point of sealing at the meeting rails. Outwardly from the lower-sash upper meeting rail and=inwardly from th'e upper sash lower rmeetin'gfirail extend flanges. 34 and 3B which are adapted to overlap and have: pressure contact when the sashes are closed, thus providing a second sealing point between theimeeting rails of the sashes, the two pressures abovementioned bein'g in directions substantially normal to each other. To provide an additional weather seal between the meeting rails of the asashes a substantially V- shaped resilient, metallic (preferably stainless steel) weather strip is disposed between the two pairs of aforesaid overlapping flanges. The flange 36 is provided with a bea'd 38 which forms a 'retaining seat for the apexof the Weatherstrip 40. Oneleg 42 of the weather strip extends'upwardly between the flanges 3B and 35. The other leg 42 of 'the'weather strip. also extends upwardly between saidi'fianges and its free end and adjacent iace areadapted to forcibly engage the inner Jface of the downwardly extending portion of the flange 30 when ithe sashes are open; when the sashessare closed, however, the upwardly extending portion of thewfiange 'ztlies betweensai-d inner face of said fiangetfl and said leg of the weather strip; at'which time this leg. of the weather strip forcibly engages the inner face of the upwardly extending portion of the flange 25, thus forming-athird weather seal.

In thew-above manner the window opening. is effectively weather. sealed even though it is provided with double hung slideabie' window sashes.

It has been found desirable to further seal the window opening during the colder seasons andto etfectuate'sueh sealing this invention contem amaeve 3 7 plates an auxiliary sealing assembly which shall be termed a storm window for convenience of expression.

In its preferable form the storm window includes an upper sash 46 and a lower sash 4% constructed, preferably, of extruded aluminum alloy.

The lights 58 and 58 are retained in and weather sealed in the said channels by weather sealing strips 70 that substantially completely extend around the edges of the lights. This weather sealing strip, which is resilient and preferably of stainless steel, comprises a base 72 which may seat in contactwith the light edge. From this base, spaced divergent legs 14 extend and engage the adjacent faces of the channel forming flanges of the sashes. The legs then are turned inwardly and converge toward the base as at 755 to engage both faces of the light. The forcible engagement between the leg portion i4 and the sash and between the leg portion 76 and the light is of such order of magnitude that the light is retained in the channels of the sash and is weather sealed.

The upper storm sash 36 is swingably, removably and adjustably supported on the header it of the window frame by hangers which include complemental, separable hinge members 73 and 80, one of which is vertically adjustable, as for instancethe member '18 is adjustable by means of the screw and slot arrangement 82 shown in the drawings.

that extends substantially the length of said lower rail.

Weather seals 95 and 98 are mounted in these channels as and 94 and may be provided with tongues ME! and it which are of resilient, compressible material such as felt or rubber or plastic compound.

The tongues extend substantially the length of the respective channels and the tongue Ice is adapted forcibly to engage the outer face of the frame header it and the tongue H02 is adapted forcibly to engage the sill I2 when the storm window is closed. This arrangement weather seals at the top and bottom.

The sides of the storm window are weather sealed as follows (see Figure 6) 2 each side railof each sash es and 43 is provided with a laterally extending flange 104 which flange thence extends inwardly as at E06 and thence backwardly on itself as at N38 to complement a 'flangeiiii that extends inwardly and thence laterally, as at H2, toward the portion I88 of the flange [04 to, together, form a channel HAthat has an open throat that extends substantially the length of said sash side rail. A compressible, resilient r 4 weather seal i it is mounted in each side channel and may have a tongue portion H8 extending from said throat and which'is adapted forcibly to engage the adjacent face of the frame jambs M- as at I26 to Weather seal the sides of the storm window.

The form of the weather seals above described is the preferred embodiment, but it will be understood that other forms of weather seals may be employed.

7 The storm window may be constructed as one unit but as above indicated it is preferably formed of two sashes su chas illustrated at it and 58. In this construction the upper sash it is retained in position on the window frame by clips 222. Each of these clips comprises a body portion H24 that is adapted to be secured to the jamb and a resilient cam latch are which is adapted to engage the adjacent flange 84 to retain the sash in position. The cam form and resiliency of the latch makes it possible tosnap the sash into its operative and secured position.

The lower sash As is supported by the upper sash at as follows: The lower rail of the upper sash ie is provided with a separable hinge element i213 and the upper rail of the lower sash is provided with a complemental separable hinge element its. The hinge element we is in the form of a flange that extends outwardly, at 32,

downwardly, at 135, inwardly, at led, and thence upwardly at 13%, forming a trough shaped in-,

V wardly opening lip. The hinge element lSii comprises an outwardly extending flange Md that thence extends downwardly at I42 terminating in a beadlike edge its that loosely pivots in the troughlike lip 538 to permit the sashes to swing relative to each other.

It will be noted that the flange hill is spaced from the flange i222; extending inwardly from the flange M0 is a shelf, I46 which establishes a condensation receiving space his to receive the Water of condensation that flows from the upper sash st to the shelf it. t the inner portion of the shelf- MS a lip 58 extends upwardly of the upper sash to receive and retain the water of condensation on said shelf and to permit it to flow outwardly to be released from the ends of the trough of the lip I38.

t will be seen that the installation and removal of the upper and lower sashes is a relatively simple operation that can be effectuated from the inside of the room. It is simply necessary to engage the separable hanger or hinge members it and st while the lower end of the upper sash is outwardly swung and to then swing said lower end inwardly past the latches 226 which will cam outwardly and then automatically move to locking position. The upper sash having been thus placed the bottom of the lower sash 3 is placed outwardly somewhat further than is shown in Figure 4.- and the bead of the flange i ls engaged in the trough ofthe lip 138; Thus engaged the lower sash will be supported by the upper sash and the lower end of the lower sash may then be swung inwardly to close the window. As the upper sash is swung to closed position the weather sealing tongue i s will be forcibly engaged with the frame header and as the lower sash is swung to closed position the tongue I62 will be forcibly engaged with. the frame and sill M. Moreoverthe swinging of the sashes to closed positions as described will forcibly engage the side sash weatherseals i it with the frame as shown in Figure 6.

"It is to be noted especially that it is convenient for the installer to observe the hinge elements i8 and 83 from the inside of the room which will, of course, facilitate interengagement of these elements. Moreover, from the inside of the room the installer may observe the open inside position of the trough lip I38 between the lower rail of the lower main sash and the lower rail or the upper main sash when the former is raised to permit the installation of the storm sashes. This will make it possible easily to engage the interengaging flanges I30 and I32 during the installation of the lower sash 4B.

In order that both the upper and lower sashes 45 and 48 may be locked in closed positions there is provided a locking arrangement in connection with the lower sash. In the illustrated embodiment at least one pivoted latch is employed. This latch, which is pivoted to the lower sash at I52, includes a detent portion !54 which is preferably resilient and a thumb piece I56, the detent portion being adapted to be pivotally moved into forcible engagement with the window frame or upper main sash stop I 58 with which, because of its form and characteristics, it has a cam locking action. I

In order that the lower sash 43 may be held in open position such as shown in Figures 4 and stay bars I00 are provided. These stay bars may be pivoted to the window frame at I62 at both sides the sash and have slidable pivotal connection with th sash through the pins I54 and slots I52.

In order that the sash s may be interchangeable with a full length screen the invention contemplates the use of a sash I53 such as shown in Figures 7, 8, Qand 1c. ihis sash is provided on its upper rail I70 with a hinge element I72 adapted to .interengage with the hinge element 18 already described to support the sash. This sash may be provided with a screen I'M, with a strengthening bar I16 which carries a finger pull clip I78, and with the latch, indicated by I80 in Figure 9, which is of the construction already described. The upper rail of the sash I58 is provided with an inwardly extending sea-1 I82 which is adapted to engage the frame header,

the lower rail is provided with a downwardly extending seal I34 adapted to engage the sill and the side rails are provided with inwardly extending seals I86 adapted to engage the frame jambs.

As in the case of the upper sashes 45 this sash I68 may be secured in position by the clips I24. The lights of either or both of the sashes 4B and 48may be glazed or screened. Thus it will be possible to combine these sashes to produce various combinations of screened and glazed sashes.

Moreover, when it is desired only to use the lower sash 48 as ascreen sash the sash may be adapted to such use. To effectuate this adaptation the clips 52d are provided with notches or hangers I88 for the reception of trunnions I90 the selective interchangeability of upper and lower screen sashes with the storm sashes, as well as the replacement of the storm sashes by a single or full length screen; and the invention contemplates a novel mounting of and sealing of the above referred to window construction elements.

I claim:

In a window construction including a stationary upper sash having a lower rail, a lower sash having an upper rail, means hinging the lower sash to the upper sash ior swinging movements of the lower end of the lower sash outwardly in a direction substantially normal to the plane of the upper sash for removably attaching said lower to said upper sash and preventing the removal of said lower sash from said upper sash except when the lower end of said lower sash extends outwardly from the plane of the upper sash and said lower sash is lifted verticaily, said means comprising: a flange extending downwardly from the lower rail of the upper sash and thence inwardly and upwardly to form a trough-dike hearing member having an edge spaced from said lower rail; a flange extending outwardly from the upper rail of said lower sash in vertically spaced relation to the adjacent face of the lower rail of said upper sash and over said edge and thence downwardly and terminating in an edge pivotally resting in said trough-like bearing member; the adjacent faces of said lower and upper rails being spaced apart to permit the downwardly extending portion of the hangs on the lower sash to be lifted over the edge of the upwardly extending portion of the flange on the upper sash when the lower edge of the lower sash is moved pivotally outwardly; said space between said lower and upper rails extending from the inner surface of the upper sash to said troughlike member; and an upwardly extending lip on said upper rail of said lower sash for directing moisture of condensation from the inner surface of said upper sash to said space and thence to said trough-like member; said lip also extending inwardly beyond the plane of the inner surface of the upper sash.
